Miri River is the body of water that splits Miri Peninsula and the mainland Miri, flowing out to sea from inland, curving at Lutong Town. In one particularly popular but inaccurate online map service, the river is incorrectly marked as Sungai Baong. Others references online have confused it with Baram River.

The Krokop Cemeteries consist of a Malay/Muslim cemetery and the Chinese cemetery right along the banks of Miri River. The cemeteries start from the Boang river bridge (connecting Miri River) to Krokop 1 roundabout alongside Miri River.
